I have written a report for the International Broadcasting Trust on how the new media environment is impacting on the way we communicate for change. It is particularly aimed at international NGOs. You can access that here. You can find details of the launch event on November 7th here.
It was based on a much longer and more wide-ranging exploratory paper that has a much wider theoretical discussion, more detail on the case studies and much more extensive footnotes and references with links to sources. You can buy that as a Kindle ebook here. Or you can download the pdf of the paper here: Communicating For Change
You can see the slides for my presentation at the launch here
